std::layout_right::mapping
Defined in header
<mdspan>
template< class Extents >
class layout_right::mapping;
(since C++23)
class layout_right::mapping;
The class template layout_right::mapping controls how multidimensional indices are mapped in a row-major manner to a one-dimensional value representing the offset. The mapping has stride 1 at rightmost extent and strides increase right-to-left as the products of extents.
Every specialization of mapping is a LayoutMapping and a TriviallyCopyable type which satisfies regular.
The program is ill-formed if the size of the multidimensional index space Extents() is not representable as a value of type Extents::index_type when Extents::rank_dynamic() is 0.
